PickPack turns Shopify orders into optimized pick lists sorted by shelf location. Smart batching groups orders so staff walk shorter warehouse routes. Items are picked one at a time with barcode scanning using hardware scanners, camera, or manual entry. At packing, every item is scanned again to verify accuracy before shipping. Staff get a mobile portal via secure link with no Shopify account needed. Managers track pick times, pack accuracy, and fulfillment stats in real time.
